Function: key llDetectedOwner( integer number );

Returns the key (UUID) of the owner of the object.

• integer number Index of detection information

number does not support negative indexes. Returns an empty key if number does not relate to a valid sensed object


llDetected* functions only work if called from within Detection events (collision, collision_start, collision_end, sensor, touch, touch_start, touch_end) or in functions called by Detection events. They will fail silently and return unusable values if called during other events.


  • If number is out of bounds the script continues to execute without an error message.
  • Events that enable the llDetected* functions always return at least one detected item.
    • Detection events are not raised if there is nothing detected.[1]
    • The detection event's items detected parameter is initially never less than 1.[2]

    collision_start(integer num_detected)
        string output =
            "\nkey of colliding object's owner ... or the colliding avatar: " + (string)llDetectedOwner(0)
            + "\nkey of this object's owner: " + (string)llGetOwner()
            + "\nname of colliding object/avatar: " + llDetectedName(0)
            + "\nkey of colliding object/avatar: " + (string)llDetectedKey(0)
            + "\nkey of the prim containing this script: " + (string)llGetKey()
            + "\nkey of this object's root prim: " + (string)llGetLinkKey(LINK_ROOT);        
        llSay(0, output);


If the detected type is an avatar the key of that avatar is returned. Avatars are owned by themselves. llGetOwnerKey works the same way with regards to avatar UUIDs.

  1. ^ The exception is no_sensor but it doesn't enable llDetected* functions.
  2. ^ Like all event parameters, the user can overwrite the initial value.
